user cannot see BU when create contract

Summary:

I have several users with similar Data Access permissions, one of them is not able to create a new contract, no list of values for Business Unit

navigate Contract Management/contracts

I notice that the user is no listed under the Manage Resources,

If I try to Add it as a Resource, we need to enter a From date, shoul it be any date ? or from when the user started as employee?, will it prevent user to enter contract with old dates?

appreciate a lot your support
